Re: tail wheel steering vs castering
One more shot; this one looking into the spring bracket from behind. It is made up of several pieces and you can see that the two 'ears' that are bent up were going to be through-bolted but I guess Corky felt that the vertical bolt from underneath was plenty since there have never been fasteners in ...

Re: tail wheel steering vs castering
Mark; see photos.

If I understand Ken correctly, that's the weak p...
